7-HOUR SORT OUT

We studied the maps till 2 hours but in vein. It was totally useless. Sometime later aunt Sofia knocked the door and said from the other side of the door "kids. Dinner's ready. Come quick." Salaam threw the pencils on the table that he was using to figure out something. He raised his hands up and said "its damn too tough. How we will be able to figure out anyway to enter the castle silently with all these thousands of maps. I think this plan has failed. Let's think of something else tomorrow. I'm really tired. Let's go to have dinner." He exited the room. I took a deep look at the maps. Something was sorting out but in my opinion food should not need to be waited. So I went to have the dinner. I went to wash my hands even when the last bite was in my mouth. After washing my hands, I went to the room and locked it. Then I started to study the map once more. Salaam knocked the door after an hour of my arrival in room and said, "Open the door, big guy." I opened it and told him that I was figuring something out. He said "come on. We kept on studying the map for about 2 hours but we didn't figure out a thing and you are saying that you are sorting something out." I replied with a smile "Just three words never give up." Salaam went to sleep but I stayed awake. I was still getting confused again and again by those maps. So I started making all the things on a different page. It took me around 2 hours. Then when the map was ready I started to look deep in the map. Slowly I sorted out a gutter entrance from studying the gutter pipes that were leading just outside the palace walls. Because the map was just of the palace so I wasn't able to get a view of the outer part of the walls. I also figured out that the gutter was also being used for the bathrooms of the prison. So I thought that it is good that we use the bathroom gutter to enter the prison. By the way how strange it is that prisoners want to get out of the prison and I wanted to go in. So after 7-hourstudy of maps I figured out something that would have helped us...
